The purpose of this study is to clarify generation mechanism of aerodynamic force of a hovering robot like as the hummingbird. The wing motion and surrounding flow of the flapping robot were investigated using motion analyze and flow visualized method. The wind which was assumed as the flying situation extended working area of the wing and influenced a locus of the wing. From results of PIV method, the fast oblique upward or downward flow and large vortex behind the wing, which was generated by the wing motion were observed.
